Thanks for that suggestion. It was really helpful. I think, the point
is, in XSUB.h, the macro 'dXSBOOTARGSXSAPIVERCHK' has been redefined
for novercheck but surprisingly it hasn't been done for
'dXSBOOTARGSAPIVERCHK' macro and that could be the reason why we want
to redefine it in the XS file after including XSUB.h file. Attached is
the patch that redefines 'dXSBOOTARGSAPIVERCHK' in Util.xs and SPI.xs
files. Please have a look into the attached patch and let me know your
comments. Thanks.
